The Java.util.HashSet.clone() method is used to return a shallow copy of the mentioned hash set. It just creates a copy of the set.
Syntax:
Hash_Set.clone()
Parameters: The method does not take any parameters.
Return Value: The method just returns a copy of the HashSet.
Below program illustrate the Java.util.HashSet.clone() method:
// Java code to illustrate clone() import java.io.*;
import java.util.HashSet;
public class Hash_Set_Demo {
public static void main(String args[])
{
// Creating an empty HashSet
HashSet<String> set = new HashSet<String>();
// Use add() method to add elements into the Set
set.add( "Welcome" );
set.add( "To" );
set.add( "Geeks" );
set.add( "4" );
set.add( "Geeks" );
// Displaying the HashSet
System.out.println( "HashSet: " + set);
// Creating a new cloned set
HashSet cloned_set = new HashSet();
// Cloning the set using clone() method
cloned_set = (HashSet)set.clone();
// Displaying the new Set after Cloning;
System.out.println( "The new set: " + cloned_set);
}
} |
Output:
HashSet: [4, Geeks, Welcome, To] The new set: [Geeks, Welcome, To, 4]
